Common Cancers in Dogs & Cats
Lymphoma
Cancer of lymph nodes. More common in older dogs. Can affect one or multiple nodes and organ systems. Responsive to chemotherapy in many cases.
Hemangiosarcoma
Cancer of blood vessel cells. Often affects the spleen, liver, or heart. Usually occurs in middle-aged to older dogs.
Osteosarcoma
Bone cancer, often in large breeds. Usually affects the leg bones or spine. Extremely painful if not treated.
Mast Cell Tumor
Skin cancer common in dogs. Can be low-grade (less aggressive) or high-grade (more aggressive). Varies widely in severity.
Mammary Tumors
Breast cancer in unspayed females. Risk increases significantly with age in intact females. Prevention through early spaying is highly effective.
Cancer Diagnosis at Eastex Veterinary Clinic
Diagnosis often requires multiple steps:
Physical Examination
We assess your pet thoroughly, noting any lumps, swelling, or abnormalities. We discuss symptoms and medical history in detail.
Imaging
Digital X-rays and ultrasound imaging reveal internal tumors, organ involvement, and metastasis. These help us understand cancer extent and location.
Blood Work
In-house laboratory testing assesses organ function and identifies metabolic abnormalities. Important to ensure your pet can tolerate treatment.
Biopsy
A sample of abnormal tissue is examined under a microscope. This confirms cancer diagnosis, identifies the cancer type, and guides treatment decisions.
Cancer Treatment Options
Surgery
Surgical removal of tumors or affected organs may be recommended. Surgery is often most effective when cancer is detected early and hasn’t spread.
Chemotherapy
Anti-cancer drugs target rapidly dividing cancer cells. Veterinary chemotherapy uses lower doses than human medicine, reducing side effects while maintaining efficacy. Many pets tolerate chemotherapy well and maintain good quality of life.
Radiation
High-energy radiation targets cancer cells. Effective for some cancers, particularly those in specific locations. We refer to specialists for radiation therapy.
Palliative Care
When cure isn’t possible, we focus on quality of life. Pain management, appetite support, and comfort measures keep your pet comfortable for as long as possible.
Your Pet’s Quality of Life During Treatment
Cancer treatment decisions should prioritize your pet’s quality of life. We discuss realistic outcomes, treatment side effects, and your pet’s likely response. Some treatments offer excellent chances of remission; others extend life while maintaining comfort. Together, we choose the approach that aligns with your values and your pet’s needs.
Managing Life with a Cancer Diagnosis
A cancer diagnosis is emotionally difficult. We provide ongoing support, monitor your pet’s response to treatment, and adjust care as needed. Regular monitoring exams and imaging track cancer progression and treatment response. We celebrate remission and are honest about progression.
Hope and Support Every Step
Many pets live months or years after cancer diagnosis. With appropriate treatment and supportive care, quality of life is often quite good. We’re committed to helping you and your pet face this challenge with hope, honesty, and compassion.
Cancer in Pets FAQs
Can cancer be prevented in pets?
Some cancers can be prevented. Spaying female dogs significantly reduces breast cancer risk. Limiting sun exposure reduces skin cancer risk. Regular wellness exams catch early cancers when outcomes are better.
Is cancer always fatal?
No. Some cancers respond well to treatment and go into remission. Others can be managed for extended periods. Outcome depends on cancer type, stage, and your pet’s overall health. We discuss realistic expectations for your pet’s specific cancer.
What are the side effects of chemotherapy?
Many pets tolerate veterinary chemotherapy well. Common side effects include mild nausea, decreased appetite, or temporary hair loss. Serious side effects are rare with appropriate dosing and monitoring.
How much does cancer treatment cost?
Costs vary widely depending on cancer type and treatment chosen. Surgical removal may cost $2,000-5,000. Chemotherapy may cost $5,000-15,000+ over treatment course. We discuss costs upfront and explore options that fit your budget.
